[PATCH] D112256: [FPEnv][EarlyCSE] Add support for CSE of constrained FP intrinsics, take 2

You know, I now believe that I can simplify this down to just this. The complication to treat constrained intrinsics as a memory update was put in when I added the restrictions on doing CSE across function calls. But since that restriction isn't needed I don't see the need for the rest of the complications. I don't think we need to go to heroics just for exception handlers, at least not at this time. This code is now much simpler.
